    <h2 id="cupsd-helper-8.description">Description</h2>
<p>The <strong>cupsd-helper</strong> programs perform long-running operations on behalf of the scheduler,
<strong>cupsd</strong>(8).

The <strong>cups-deviced</strong> helper program runs each CUPS
<strong>backend</strong>(7)

with no arguments in order to discover the available printers.
</p>
    <p>The <strong>cups-driverd</strong> helper program lists all available printer drivers, a subset of &quot;matching&quot; printer drivers, or a copy of a specific driver PPD file.
</p>
    <p>The <strong>cups-exec</strong> helper program runs backends, filters, and other programs. On macOS these programs are run in a secure sandbox.
</p>
    <h2 id="cupsd-helper-8.files">Files</h2>
<p>The <strong>cups-driverd</strong> program looks for PPD and driver information files in the following directories:
</p>
    <pre>
    <em>/Library/Printers</em>
    <em>/opt/share/ppd</em>
    <em>/System/Library/Printers</em>
    <em>/usr/local/share/ppd</em>
    <em>/usr/share/cups/drv</em>
    <em>/usr/share/cups/model</em>
    <em>/usr/share/ppd</em>
</pre>
    <p>PPD files can be compressed using the
<strong>gzip</strong>(1)

program or placed in compressed
<strong>tar</strong>(1)

archives to further reduce their size.
</p>
    <p>Driver information files must conform to the format defined in
<strong>ppdcfile</strong>(5).

</p>
    <h2 id="cupsd-helper-8.notes">Notes</h2>
<p>CUPS printer drivers, backends, and PPD files are deprecated and will no longer be supported in a future feature release of CUPS.
Printers that do not support IPP can be supported using applications such as
<strong>ippeveprinter</strong>(1).
